```
public class GeneratePresignedUrlRequest
extends AbstractBceRequest
```
Contains options to generate a pre-signed URL for an Baidu BOS resource.
Pre-signed URLs allow clients to form a URL for an Baidu BOS resource and sign it with the current BCE security credentials. A pre-signed URL may be passed around for other users to access the resource without providing them access to an account's BCE security credentials.
